PV modules, off-grid inverters (including PV controllers/inverters), storage batteries (lead-acid/colloid/lead-carbon/lithium ternary/lithium iron phosphate, etc.), PV mounts, cables, and distribution boxes are all important components of a PV off-grid system.

Photovoltaic modules in photovoltaic power generation is the most important equipment, in the daily installation and operation and maintenance process if there are special circumstances will cause the hot spot effect of photovoltaic modules and potential-induced decay effect (PID), for the majority of owners of the loss, so we should pay attention to control the photovoltaic power plant to avoid these two effects in the installation and routine maintenance of the power plant.

New civil building projects should make full use of building roofs, facades and other suitable space configuration of solar photovoltaic systems. Solar photovoltaic systems follow the principles of safety, reliability, coordination and aesthetics, economical and applicable, and building projects synchronized planning, synchronous design, synchronous construction, synchronous acceptance and put into use, the cost of its construction unit according to the actual investment in the project costs. Actively carry out the design and construction of photovoltaic building integration, encourage the use of photovoltaic roofing materials, photovoltaic glass curtain wall and other building materials type photovoltaic components.
